GA-R1/C1: the merge commit itself cannot carry a doc edit, so the merge is
recorded here in a follow-up commit -- the same shape Stage 4 used (merge
6f5701d recorded by 1023596).

States explicitly that no stage opened or closed, cites the post-merge
gauntlet (81) and repo-lint, and flags that both figures are read under R15:
the harness count is compared against the record by hand because the manifest
R15(2) rules is not built, and repo-lint emits no files-scanned figure, which
is R15(1)'s finding observed rather than assumed.
